The Hague breathes peace and justice. The ambition of 'Stichting The Hague UNited for Peace and Justice' is to build on this foundation with the aim to give peace & justice an important place in the hearts and actions of our inhabitants, entrepreneurs and organizations. The foundation connects educational institutions, cultural institutions, international organizations and NGOs that are promoting and working on peace and justice in The Hague. Since 2014, the partners organize activities during the Just Peace festival in the week leading up to the International Day of Peace of the United Nations on 21 September. The program of the festival consists of a mix of debate, performing arts, museum activities, sports and music, during which peace & justice are the main themes. The Just Peace festival annually attracts around 40,000 visitors. Since the beginning of 2018, in addition to the festival in September, the partners have started to organize peace & justice activities throughout the whole year.

The current institutions cooperating with the foundation are the Peace Palace, Museon, ProDemos, the Oranjehotel Foundation, The Hague Historical Museum/The Prison Gate, Humanity House, University Campus The Hague, The Hague Bridge, The National Theatre, HagueTalks and Peace in the Park.
